That’s because magnets will stick to a person’s stomach and intestines, causing serious injury or even death. Luckily, surgeons removed the BuckyBalls from Payton’s stomach in time, and then were able to repair the internal tears they caused.

“In all the research I have done, I have never seen any child swallow more than 10 magnets,” said Sandy Nipper, a nurse at Randall Children’s Hospital in Portland, Oregon.

“I’m thinking that she kind of put two and two together and thought these look like what we put on Christmas cookies,” explained Kelli Bushnell, Payton’s mom. “If we had any idea what those magnets could have done to our daughter’s intestines I would have never had them in our house.”
